ASX Dual Listing

Capstone intends to apply to list as a Foreign Exempt Issuer on the Australian Securities Exchange (“ASX”) during the first quarter of 2024. The Company has grown a substantial investor base in the Asia Pacific region and this strategy will broaden Capstone’s exposure within these markets. The Company does not intend to raise capital as part of the listing on the ASX and Capstone’s common shares will continue trading on the Toronto Stock Exchange, its primary listing.

The ASX is a premium market with a long track record as a platform for mining companies. It provides a deep and liquid pool of sophisticated investors and market participants who are limited or restricted to only ASX-listed issuers and have a strong understanding of the mining business.

Appointment of New Director

Capstone also welcomes Gordon Bell as a new Independent Director effective January 8th, 2024. He was most recently Vice Chairman for the Mining and Metals Group of RBC Capital Markets before his retirement in 2022. Previously, Mr. Bell was the Global Head for RBC’s Mining & Metals group, leading the expansion and growth of the firm’s Mining and Metals practice domestically as well as in London, Australia and Asia, establishing RBC as a leader in the sector globally.

Mr. Bell has global expertise in corporate strategy, debt and equity financing, shareholder engagement, and mergers and acquisitions. He received a Bachelor of Science in Mining Engineering from Queens University in Kingston, Ontario and an MBA from Washington University in St. Louis, Missouri.
